Yam tseem ceeb rau xaiv Pore Loj ntawm Chromatographic Filter Discs
Kev sib txuam ntawm HPLC lim disc pore loj thiab qhov tseeb daim ntawv thov scenarios yog lub hauv paus ntsiab lus kom lav ruaj khov, rov ua dua thiab raug chromatographic xeem cov ntaub ntawv. Qhov muag tsis pom kev mus nrhiav ultra-siab precision lossis cov kua dej ntau dhau yuav ua rau qhov sib npaug ntawm cov chromatographic system thiab cuam tshuam rau cov txiaj ntsig kev xeem. Rau cov kws ua haujlwm hauv chav kuaj thiab cov khoom yuav khoom, cov hauv qab no peb lub hauv paus loj xaiv cov qauv rau 316L sintered stainless hlau lim discs yuav tsum tau ua raws li nruj me ntsis raws li:
Ua ntej, phim cov ntsuas qib.
UPLC ultra-cov cuab yeej siab siab precision yuav tsum tau txais 0.2μm ultra-fine pore loj lim discs kom hloov mus rau ultra-fine packing thiab micro-channel pipelines; HPLC cov cuab yeej txheem txheem tuaj yeem xaiv 0.5μm universal pore loj kom sib npaug tus nqi thiab kev ua haujlwm.
Qhov thib ob, phim tus qauv purity.
Rau siab -purity purity trace analysis, ultra-precision pore size filtration yog yuav tsum tau kom tsis txhob muaj impurity cuam tshuam; rau kev lag luam crude qauv nrog ntau impurities, graded pom nrog loj pore loj + nruab nrab pore loj + precision pore loj tuaj yeem ua tau zoo rau kev pab cuam lub neej ntawm chromatographic kab thiab precision lim ntsiab.
Thib peb, phim lub siab ua haujlwm ntawm cov khoom siv chromatographic.
Feem ntau, qhov me me ntawm qhov pore loj ntawm sintered lim disc, qhov siab dua cov dej tsis kam thiab lub zog rov qab siab. High-siab UPLC systems tuaj yeem ua rau muaj kev tiv thaiv me ntsis coj los ntawm 0.2μm ultra-fine pore loj lim discs. Hauv qhov sib piv, qis-siab cov pa HPLC cov tshuab yuav tsum tsis txhob siv ultra-fine pore loj frits los tiv thaiv lub cev rov qab siab, cov khoom siv tswb thiab txawm tias cov kav dej puas.
Vim li cas Uniform Pore Size Consistency Matters rau Chromatographic Test?
Qhov sib txawv ntawm cov khoom siv lim dej zoo tib yam, HPLC thiab UPLC sintered lim frits muaj cov kev cai nruj heev rau qhov pore loj uniformity thiab cov qauv kev ruaj ntseg. High- zoo 316L sintered stainless hlau lim discs txais cov hmoov av nqus sintering tshuab, tsim ib qho kev sib txuam, peb - qhov sib txuas ntawm qhov pore qauv nrog cov pore zoo ib yam. Qhov ruaj khov thiab cov pore loj ua kom zoo ib yam ntawm cov theem ntawm lub xov tooj ntawm tes ntws tawm hauv lub chromatographic kem, ua haujlwm zoo kom tsis txhob muaj kev kub ntxhov, kev tsis ncaj ncees thiab cov ntim hauv zos tuag, thiab kev daws teeb meem ntau yam chromatographic xws li peak distortion, peak bifurcation, trailing peaks thiab lub sij hawm tuav tsis ruaj khov.
Tsawg- cov lim dej zoo nrog qhov tsis sib xws ntawm qhov pore loj thiab cov qauv tsis ruaj khov yuav ua rau cov kua dej tsis sib haum hauv zos, ua rau cov qauv tsis sib npaug ntawm qhov nrawm thiab qhov hloov pauv hauv lub hauv paus, uas ua rau puas tsuaj rau qhov rov ua dua thiab raug ntawm cov ntaub ntawv sim. Hwm chromatographic-qib 316L sintered lim discs feature ib tug nruj pore loj, ua tau raws li thoob ntiaj teb siab -precision chromatographic xeem qauv thiab ntev- lub sij hawm ruaj khov kev khiav hauj lwm yuav tsum tau.
